Round Slings

Rope Services Direct manufactures the majority of our round slings in-house due to investments we have made in the latest sling-making technology. The slings are available in a range of widths and safe working loads and lengths from 1 to 12 meters. The standard colour coding format applies to all our round slings in order to easily identify the safe working load of the sling.

  • 1 tonne = purple
  • 2 tonne = green
  • 3 tonne = yellow
  • 4 tonne = grey
  • 5 tonne = red
  • 6 tonne = brown
  • 8 tonne = blue
  • 10 tonne = orange.

Slings can be manufactured in 2-3 working days to your requirements. Information lables are clear on all round slings.  Rope Services Direct can also supply other types of lifting slings, including flat web slings, wire rope slings and chain slings.

About Round Slings

Round slings protect from damage to more delicate loads. This is due to the soft and flexible nature of these round slings which are made from 100% polyester webbing. They are great for round or cylindrical objects.

The seamless tubular cover is non-load bearing and acts as a protective cover around the load bearing core. The covers have excellent wear and abrasion resistance over its entirety partly because there are no seams or edges to rub against loads and components, it is often edges and seams which wear out first.

The inner core is the load bearing part.  The core is made from polyester yarn hank which is twisted and wound together. This provides great strength and durability. These slings will flatten during use to better grip the load; this will not detract from its safe working load.

Safe Slinging

As with all lifting slings safe slinging procedures must be followed at all times. The angle of the lift (this is the angle the sling takes from a vertical plane) , hitch type and safe working load should all be taken into consideration. The chart below should help to identify the reduction required to the SWL at various angles and with each hitch type.

Safe use of Round slings

  • Slings used in a basket hitch must have the load balanced to prevent slippage.
  • Slings must always be protected from sharp edges, protrusions or abrasives
  • Determine the weight of the load, which must be within the rated capacity of the sling.
  • Slings with fittings used a choker hitch must be of such a length to assure that the choking action is on the webbing, and never on a fitting.
  • The opening fittings must be the proper shape and size to ensure that the fitting will seat correctly in the hook.
  • Select sling having suitable characteristics for the type of load, hitch and environment.
  • Don’t load a sling in excess of the rated capacity. Taking into account the load angle which effects the rated capacity.
  • Do not drag slings on floors or abrasive surfaces. Don’t twist or tie slings or join in knots.
  • Slings shall not be pulled from under loads if load is resting on sling.
  • When lifting in a chemically active environment, make sure sling materials are compatible with each chemical.
  • Do not drop slings with metal fittings
  • Don’t pull on the sling when loaded.

More Tips

  • Never store wet slings, clean with water and dry thoroughly, ALWAYS store in a cool dry dark place.
  • Sun/ultraviolet light degrades the strength of slings.
  • Hitch the sling in a manner providing control of the load.
  • Personnel must keep clear of the suspended load, and from between the sling and load, and between sling and crane/hoist hook.
  • Personnel must not ride the sling
  • Don’e use a sling at temperatures above 80⁰c or below 0⁰c
  • Do not shock load
  • Do not twist or kink legs.
  • Loads must be centred in base of hook.
  • Slings must be long enough so that the rated capacity is adequate. Including when the angle of the legs is taken into account.
  • The sling legs shall contain or support the load from the sides above the centre of gravity when using a basket hitch.

SLING ANGLE AND SLING LOAD CHART

The sling angle is the angle measured between a horizontal line and the sling leg or body. This angle is very important  and can have a dramatic effect on the rated capacity of the sling. As shown, when this angle decreases the load on each leg increases. This principal applies whether one sling is used to pull at an angle. In a basket hitch, or for multi-legged bridle slings. This data is only for equally loaded sling legs. Do not use angles of less than 30 degrees.

INSPECTING YOUR ROUNDSLINGS:

INITIAL INSPECTION:

Before any new or repaired sling goes into service it needs an initial inspection. A designated person should ensure that the correct sling is being used. They should also determine that the slings meet the requirements and has not been damaged in shipping.

FREQUENT INSPECTIONS:

Before every use of a sling a frequent inspection should be made for fault finding purposes.

PERIODIC INSPECTIONS:

This is a thorough inspection which is carried out by competent personnel. The frequency of inspection should be based on:

Frequency of sling use.

Severity of service conditions.

Experience gained on the service life of slings used in similar applications.

Carry out thorough inspections every 6 months. Records of inspections must be kept on file.

Examine slings prior to every use. Look for signs of deterioration including, snagging, holes, tears, cuts, broken or worn stitching, knots, burns or excessive abrasive wear.
